Original No. 2,224,351, dated December 10, 1940, Serial No. 265,192, March 31, 1939. Application for reissue April 23, 1941, Serial No. 389,897

10 Claims The invention relates to materials to be used in the construction of houses or other buildings as weatherproof fiber board siding to take. the place of wooden siding and weatherboarding for theputer wall covering for houses or. buildings. The material also may be used as a veneering for walls of buildings where it is desired to simulate brick, tile or other selected finish'of a highly diversified character.

It is accordingly the obiect of my invention to provide a material suitable for construction of walls made of fiber board, paper board, etc. which is formed with additional material and provided with a finish or .outer layer or coating of material which makes it available as an outside wall construction. material.

A further object of the invention is to provide a new process of manufacturing building covering units of the type hereafter to be described, wherein by the steps taken the units are reinforced so that they will withstand hard abuse and be more rigid when applied than ordinary siding units.

Other objects and advantages will be more apparent from the following description wherein, 25

reference is to be bad to the accompanying drawmg, upon which I I Figure 1 is an elevational view showing the face of the unit.

Figure 21s a view of the edge of the unit shown in Figure 1.

Figure 3 is an elevational view of the back of the unit shown in Figure 1.

Figure 4 is a view of the end of the unit shown in Figure 1.

Some of the features of the invention include the reiniorcingelements, the arrangement of the units to form a wall covering, their proportionate lengths in relation to the spacing between disthe vertical joints of a contiguous horizontal row, and generally, all details 01 the construction of the units.

The length of the units shown in Figures 1 and 3 are ordinarily about. 48%" and the width is ordinarily about 15%". Each unit in this instance engages four studs, the distance between the studs being about 18". The long dimension the slab is transverse to the studding and the end overlappinl or abutment of contiguous slabs of the horizontal rows, preferably takes place on the studdins.

A fiber or other type board It is preferably dried to remove all of the moisture or render the board substantially bone dry at about 400' F. 55

The hot dry board is then surface impregnated with hot waterproofing compound such as asphalt, tar, wax, and the like. After the surface of the board has been surface impregnated or coated as by spraying with hot asphalt or the like, the excess impregnating or coating cornpound may be removed by mechanical means such as squeeze rolls or scrapers. It is not absolutely essential that the excess waterproofing compound be removed by mechanical means.

The coated or impregnated board is'dried or bakedin a high temperature oven at about 350 to 450 F. When the baiting operation is complete the board containing considerable heat and the impregnated or coated fibers are soft and pliable. While the unit is in this condition, it is passed between one or more pair of calendering rolls. The calendering rolls burnish or smooth the surface waterproofing compound and fibers thus sealing the back surface and giving such surface a vapor prooi finish. The finish is generally smooth and glossy and may be termed a vapor barrier.

The board while still hot is passed through what is termed an impress roll having thereon the design shown in Figure 3. There isjormed on the back of the board imprint lines I! which preherably are about of an inch in depth. The action of the impress roll is to drive the waterproof-- ing compound deeper into the board along the lines I! which forms a series of inverted beads. These beads give added the board, and furnish the applying mechanic with guide lines for cutting or dividing the unit on the job. The lines ii are preferably aligned with the mortar joints or bars IS on the face of the units and the waterproofing compound, penetrating to a greater depth than normal as mentioned above, extends inward a substantially greater distance than at those portions which are not impressed. Too deep scoring may overcome the stifiening and fiber cementing action,

of the waterproofing compound and actually weaken the board. Too deep scoring should therefore be avoided so that the advantage of astronger board is not lost.

i The board, "I now has applied a suitable mastic II to one surface. granular material i2 is spread over the surface thereof. The granules are now pressed into the mastic material.-' The unit is now passed to a suitable embossing roll where brick simulating elements or the like is formed. Between each element l3 and it are formed mortar simulating lines Ii.

strength and rigidity to I While the mastic is hot.

These mortar simulating lines II are normally used as nailing strips since it is one of the main with the mortar ba purposes of the entire structure to give the appearance of masonry and a nail head in the middle of a brichwould spoil the elect.

Such normal use of the mortar Joints may be seen in Patent No. 1,886,363 granted November 8, 1932, to Aufderheide and Patent- No. 2,226,265

filed July 7,1936, by Sullivan et al. which are deemed to be representative of the general practice in this respect at the time filing of the original application on which the present reissue application is based.

The board Il may be shiplapped as at It so that tight joints, are provided with adjacent units. These unitsmay besecured directly to the studding or may be used as a veneering for walls and thelike. In either instance the units are preferably secured in. place by suitable fastening means such as nails. The fastening means pass through the unit preferably at the mortar Joints II, and into the studding.

As mentioned above the headings ll give added strength and rigidity to the board by driving the waterproofing compound deeper. The compound cements the fibers together and also stifi'ens the individual fibers themselves. The added strength greatly increases the gripping action of the fibers on the nail orother fastening means driven into the board. The mortarjoints I 6 serve as quick andready guide means indicating the best nailing areas of the board. P

In the preferred size the units are 48%" long and wide, this gives a covering surface of 48 by 15" as shiplap is preferably employed.

2.
